BroydenFindRoot Method

public static double[] FindRoot(
	Func<double[], double[]> f,
	double[] initialGuess,
	double accuracy = 1E-08,
	int maxIterations = 100,
	double jacobianStepSize = 0,0001
)

Parameters

f  FuncDouble, Double

The function to find roots from.

initialGuess  Double

Initial guess of the root.

accuracy  Double  (Optional)

Desired accuracy. The root will be refined until the accuracy or the maximum number of iterations is reached. Default 1e-8. Must be greater than 0.

maxIterations  Int32  (Optional)

Maximum number of iterations. Default 100.

jacobianStepSize  Double  (Optional)

Relative step size for calculating the Jacobian matrix at first step. Default 1.0e-4
